STRIPPING MECHANISM FOR CARDING-ENGINES.

Application filed. June 3, 1912.

To all 207mm it may concern:

Be it known that we, JOHN MIDGLEY and THOMAS GANDY MILLs, both subjects of the King of Great Britain, the former residing at Rovinwood House, Todmorden, in the county of York, England, and the latter at Stoneswood House, Todmorden aforesaid, have invented new and useful Improvements in and in Connection with the Stripping Mechanism for carding-Engines, of which the following is a specification.

Our invention relates to improvements in and in connection with the stripping of the main cylinders and doffers of carding en gines and the removal of waste and dust therefrom.

Various forms of apparatus have been designed for the purpose of carrying away the dust and dirt caused by the stripping of carding engine cylinders and doffers, the best known types of these devices being the exhaust system in which the dust is drawn off through suction pipes in connection with an exhaust fan and the vacuum system which draws both dust and strip and is worked in connection with an air pump.

Our invention consists essentially in employing a rotating stripper applied to the stripping brush as used on the main cylinder and dofi'er, such rotating stripper and brush being inclosed in a casing connected by a pipe preferably a flexible or swing pipe to an exhaust pipe through which the waste and dust taken off by the stripping brush from the main cylinder and dofl'er and re moved therefrom by the rotating stripper is conveyed to the usual dust cages of a scutcher or to separate dust cages of a like nature, whereby the dust and dirt are separated from the fiber which is either delivered loosely or passed forward through a beater and converted into a lap.

The rotating stripper may be of any suitable type, as for example a series of say four combs or rows of teeth or needle pointed pins mounted longitudinally on a drum or cylinder which is driven preferably in the same direction as the stripping brush or cylinder at the point of contact but at a quicker surface speed so as to more readily strip the waste from the teeth of the strip ping brush.

Ne illustrate an embodiment of our invention in the accompanying four sheets of drawings, in which Figures 1 and 2 are a plan and end ele- Specificaticn of Letters Patent.

vation respectively of the general arrangement of a carding room fitted with our improved stripping mechanism. Figs. 3and 4L are a front and end elevation respectively of our improved mechanism as applied to stripping and removing the waste and dust from the cylinders and doifers of carding engines.

Similar letters refer to similar parts throughout the several views.

Referring to Figs. 1 and 2, in these views a designates the carding engines and Z) the exhaust or suction pipes for conveying the waste fiber and dust from the carding engines a; to the dust cages and fan 0, 1n the scutching room (E, which separate the dust and fiber, the dust dropping into the dust fine 6 and the fiber being fed or drawn from the cages and delivered to the scutchers or to a waste bag if separate dust cages of a like nature are employed. From the exhaust or suction pipes b are flexible or swing branch pipes b to each of which is attached either temporarily or permanently our improved stripping mechanism f so that it can be applied to either the cylinder 9 or the doffer it, as shown in Fig. 2.

We illustrate an arrangement of our stripping mechanism as applied to the main cylinders and doflers on a larger scale in Figs. 3 and 4. In these views the stripping brush 6, which is covered with card clothing or other suitable stripping means, is used on the main cylinder 9 and dofi'er 7b and is carried on a shaft 2" and supported in the usual bearing brackets of a card brush driven by the pulley j. Upon this shaft 2" are mounted brackets is which fit on the bend or frame of the engine and support a shaft Z driven from the shaft 2" by any suitable means such as the crossed belt m and the pulleys n and 0 in the direction indicated by the arrow but at a quicker surface speed than the brush c. The rotating stripper carried upon the shaft Z may be of any suitable type, for example as 'shown, it may consist of a series of four combs or rows of teeth or needle pointed pins 79 mounted longitudinally on a drum or cylinder or, as shown, on four arms 29 The rotating stripper and brush 2' are inolosed in a casing '1" and connected by the branch pipe I) to the exhaust pipe I) through which the waste and dust removed from the main cylinder and dolfer are conveyed to the dust cages. This arrangement has many advantages over existing systems as the fiber does not become flocked or matted but is delivered loosely and is separated in the scutching room by the dust cages from the dirt in one continuous operation. Further by our arrangement a clean side of the brushz' is always presented to the card cylinder or doiier. The waste emerging from the dust cages is much cleaner and a considerable amount of nep is. extracted from the waste thus increasing its value.

The apparatus may be used as an intermittent or a continuous stripper.

l'fdesired the separated waste fiber can be fed directly into a lap machine and converted into a lap.

What we claim and desire to secure by Letters Patent is 1. In combination, a rotary stripping brush, adapted to strip the main cylinders and dofiers of carding engines, a rotary stripper operatively associated with said brush for removing the waste and dust there from, a casing within which said brush and stripper are mounted, a dust cage, an ex haust pipe leading to said dust cage and a conduit extending between said casing and said exhaust pipe, said conduit communicating with said casing at a point midway between the end walls thereof.

. 2. In combination, a rotary stripping brush, adapted to strip the main cylinders and doifers of carding engines, a rotary stripper operatively associated with said brush for removing waste and dust therefrom, means for rotating said brush and said stripper in opposite directions and at different surface speeds, a'casing within which said brush and stripper are mounted, a dust cage, an exhaust pipe leading to said dust cage and a conduit extending between said casing and saidexhaust pipe, said conduit communicating with said casing at a point midway between the end walls thereof.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
